2015 Mercedes c400 w205 stage 1 tune problem check engine light
Hi I have a 2015 Mercedes c400. The problem is I have a check engine light saying I have a misfire on all 6 cylinders. The car was running fine no problems then I get a stage 1 tune and the car runs fine see no problems although a check engine light came on saying it's misfiring at all cylinders.
Is the tune the problem ?
or it's possible that I just need new spark plugs for all cylinders ?

how many miles on the plugs? interval is 46k and its recommended to stick with that, especially if tuned.
